from The Century Dictionary.

• To cause to muse; absorb or engage in meditation; occupy or engage wholly; bewilder; puzzle.
• To keep in expectation, as by flattery, plausible pretenses, and the like; delude; keep in play.
• To fix the attention of agreeably; engage the fancy of; cause to feel cheerful or merry; entertain; divert: as, to amuse an audience with anecdotes or tricks, or children with toys.
• Synonyms Amuse, Divert, Entertain, Beguile, occupy, please, enliven. Amuse may imply merely the prevention of the tedium of idleness or emptiness of mind: as, I can amuse myself by looking out at the window; or it may suggest a stronger interest: as, I was greatly amused by their tricks. Divert is to turn the attention aside, and (in the use considered here) to something light or mirthful. Entertain is to engage and sustain the attention by something of a pleasing and perhaps instructive character, as conversation; hence the general name entertainment for lectures, exhibitions, etc., designed to interest in this way. “Whatever amuses serves to kill time, to lull the faculties and banish reflection; it may be solitary, sedentary, and lifeless: whatever diverts causes mirth and provokes laughter; it will be active, lively, and tumultuous: whatever entertains acts on the senses and awakens the understanding; it must be rational and is mostly social.” Crabb. Beguile is, figuratively, to cheat one out of weariness, of dull time, etc. The word is as often thus applied to the thing as to the person: as, to beguile a weary hour; to beguile one of his cares.
• To muse; meditate.
